You will find below the content of each of these 3 directories taken the brick on node 1:

i)/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10

drwxr-xr-x  4 www-data www-data  4 Nov  5 14:19 .
drwxr-xr-x 31 www-data www-data 31 Nov  5 14:23 ..
drwxr-xr-x  3 www-data www-data  3 Nov  5 14:19 dir11
drwxr-xr-x  3 www-data www-data  3 Nov  5 14:19 another_dir

ii)/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/
drwxr-xr-x 3 www-data www-data 3 Nov  5 14:19 .
drwxr-xr-x 4 www-data www-data 4 Nov  5 14:19 ..
drwxr-xr-x 2 www-data www-data 4 Nov  5 14:19 oc_dir

iii)/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir

drwxr-xr-x 2 www-data www-data   4 Nov  5 14:19 .
drwxr-xr-x 3 www-data www-data   3 Nov  5 14:19 ..
-rw-r--r-- 2 www-data www-data  32 Nov  5 14:19 fileKey
-rw-r--r-- 2 www-data www-data 512 Nov  5 14:19 username.shareKey

so as you see from the output above only the "oc_dir" directory has two files inside.

Thank you for explaining this important part. So yes with your help I could find the filenames associated to these 2 GFIDs and guess what? they are the 2 files which listed in the output above of the "oc_dir" directory. Have a look at this:

# find /data/myvol-pro/brick -samefile aae4098a-1a71-4155-9cc9-e564b89957cf
/data/myvol-pro/brick/.glusterfs/aa/e4/aae4098a-1a71-4155-9cc9-e564b89957cf
/data/myvol-pro/brick/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir/fileKey

# find /data/myvol-pro/brick -samefile 3c92459b-8fa1-4669-9a3d-b38b8d41c360
/data/myvol-pro/brick/.glusterfs/3c/92/3c92459b-8fa1-4669-9a3d-b38b8d41c360
/data/myvol-pro/brick/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir/username.shareKey

I hope that helps the debug further else let me know if you need anything else.
